The specs are basically almost the same (one is $2.25 cheaper and has a rear shaft, which won't hurt anything; it also is in stock which is a bonus). Biggest gripe is that the front shaft is fairly short; the factory gear will press on and should be ok, but I haven't used this exact motor. You'll want to use some red loctite or other sleeve retainer and rough up the shaft surface. I'm fairly certain it has a fan based on the model name, but the pictures aren't clear; the Banebots one definitely does.

For 20% more speed (but likely even poorer longevity), you could try the 23000 RPM Nichibo motors from Jameco ($3/ea):
